9 And he said, "Go and say to this people: "Keep listening, but do not comprehend; keep looking, but do not understand.' 10 Make the mind of this people dull, and stop their ears, and shut their eyes, so that they may not look with their eyes, and listen with their ears, and comprehend with their minds, and turn and be healed." 11 Then I said, "How long, O Lord?" And he said: "Until cities lie waste without inhabitant, and houses without people, and the land is utterly desolate; 12 until the Lord sends everyone far away, and vast is the emptiness in the midst of the land. 13 Even if a tenth part remain in it, it will be burned again, like a terebinth or an oak whose stump remains standing when it is felled." The holy seed is its stump.

Commentary on Isaiah 6:9-13
(Read Isaiah 6:9-13)
God sends Isaiah to foretell the ruin of his people. Many hear the sound of God's word, but do not feel the power of it. God sometimes, in righteous judgment, gives men up to blindness of mind, because they will not receive the truth in the love of it. But no humble inquirer after Christ, need to fear this awful doom, which is a spiritual judgment on those who will still hold fast their sins. Let every one pray for the enlightening of the Holy Spirit, that he may perceive how precious are the Divine mercies, by which alone we are secured against this dreadful danger. Yet the Lord would preserve a remnant, like the tenth, holy to him. And blessed be God, he still preserves his church; however professors or visible churches may be lopped off as unfruitful, the holy seed will shoot forth, from whom all the numerous branches of righteousness shall arise.
